METAL T? v Application filed. December The present invention pertains to a metal screen for doors or windows which has been perfected with the object/oi providing a simple, durable andcconomical structure including a metallic frame molding, which can be shipped in knock-down condition and easily asfembled on the premises by any handy man, contractor or owner. 1

A more specific object of the invention In is to provide a frame construction for this purpose having mullions which divide the screen into panels. so that in case anypartof the netting becomes damaged, one of the panels may be replaced at very little cost instead of covering the entire frame with new netting at nearly the cost of a new screen. The mullions also make the screen more rigid so that it-is less likely to get out of shape or sag. In this construction, the mullions may be arranged in a number of differentdesigns to harmonizewith the various styles of windows with which a the screens are to be used.

The specific construction of the invention and the advantages thereof will be more fully explained in the following detailed description, which is to be read in connection with the accompanying drawings show-v ing the preferred embodiment of the 30 invention. H

In the drawing,

a full sizevwindow screenhaving metallic sideand end rails 10. each in the formot' channels having at one side an" inturned' flange 11, and at the otherside a right angularly disposed flange" 12, the edge of" which is bent inwardly; as at '18.

The side and end rails have mitered ends, which areadapted to be held in abut' Figure 4 is an enlarged view of an inte rscanner. r

ting relation to form the 'corners of the o frame At each corner is a corn'erpiece it, having branches l5- exten ding 'at right angles to each other; and'adaptedlto overlie the adjacent portions of the rails 10 between the flanges 11 and 12; Each rail 10 also is adapted to receive a clamping strip 16, whicl'i extends substantially throughoutthe length of the rail, and clamps the marginal portions of the netting 17. theret0. lflach strip'16 tormed'with a longitudinal i corrugation lti which fits over a similar corrugation 19 in the corner piece and serves to strengthen the" rails, as Well as to maintain the same in alinement withvthearms of the corner piece, i

Theside rails 10 are intermediately con nected to each other by a cross bar or mul lien 20 formed with inwardly inclined opposed side flanges 21; and having at each end a tongue 22, which extends through a 1 slot 23 at the inner side of the rail 10. The channel formed between the side flanges 21 of the mullion is adapted to receive the adjacent edges of the netting 17, Whichare clamped therein by a partially Y folded clamping strip 24L. This clamping strip maybe inserted between the flanges 21 and subsequently spread. A number of upright mullions 25 may also be inserted between the horizontal mullion 20 andthe top and bottom rails; Each of these vertical inullions is similar to the horizontal mirllionsQO, having inwardly no a converging side flanges ,26 fa'nd end tongues Q'Zadaptd to beninserted in. slots 28 formed in the sidesjof the mullion 20. Clamping strips 29, similar tojthe strips'Q; are .,.used. cin connection with the vertical mullions25. Ordinarily the screens will 'be 'shipped in knock-down condition, so that the :freight charges are much less, and there is less like" lihood of the screens being damaged in trans it; Theassembling of the screens is a very 7 simple matter. The mullions 20 'and 25 win first be assembled, then the side and end rails 10 will be put on and connected by the corner pieces 14. The several panel's ofinet ting 17 are then laid on and securely clamped by forcing the clamping strips 16 i Qtand 29 into the respective channels. Thej entire assembly forms av rigid and durable structure which is reinforced bythe mullions," so that "it willnot get outof shape or sag. It is secu'relyheld together by the clamping strips which hold the netting, and p i i in case any part oi the netting becomes mullion terminating at'its ends in tongues damaged, it is only necessary to replace the panel wherein the damage has occurred, thus involving only avery little trouble and expense,

Nhile I have shown and describedin detail one embodiment ofthe invention, it is apparent that the relative arrangement of the mullionsand the details of their construction may be varied considerably ac cording to the style and size of the window or door in which the screen is to be used." It is to 'be'understood that the inventlon 1I1' eludes all such modifications as fall within the scope of the appended claims.
